Abstract: The disclosure provides a network equipment power supply and a heat dissipation system therefor. The heat dissipation system includes a liquid-cooling heat dissipation device and an air-cooling heat dissipation device. The liquid-cooling heat dissipation device includes a liquid inlet, a liquid outlet, and a liquid-cooling pipe between them, wherein liquid-cooling medium flows inside the liquid-cooling pipe and takes away heat generated by components arranged around the liquid-cooling pipe; The air-cooling heat dissipation device includes an air inlet, an air outlet, and an air-cooling channel between them, wherein airflow passes through the air-cooling channel and takes away heat generated by components arranged around the air-cooling channel. The disclosure conducts hybrid heat dissipation combining characteristics of liquid-cooling heat dissipation and air-cooling heat dissipation to effectively enhance heat dissipation efficiency, and provides a new choice for design of a power supply unit with high power density.
